Nearly 40 years ago, Mohring [1965] suggested this logic for planning optimal highway investment programs. He argued it could be implemented by measuring the quasi-rents generated by specific additions to an existing roadway system. This paper uses a unique set of additions to a loop roadway in metropolitan Phoenix, together with detailed records of housing sales over the past decade, to meet this need. We find that estimated increases in capitalized housing values due to four segments added during this period range from 73 to over 273 million dollars per mile of the roadway addition. aHardcopy version available to institutional subscribers. aSystem requirements: Adobe [Acrobat] Reader required for PDF files. aMode of access: World Wide Web. 7aH4 - Publicly Provided Goods2Journal of Economic Literature class. 7aR14 - Land Use Patterns2Journal of Economic Literature class. 7aR40 - General2Journal of Economic Literature class.1 aSmith, V.
